Description

Technical Field

[0001] This utility model relates to the field of auxiliary agent production technology, and more specifically, it relates to a raw material feeding device for auxiliary agent production. Background Technology

[0002] Additives are auxiliary chemical substances added to base substances to improve material properties or processing techniques. They are widely used in rubber, coatings, inks, cosmetics, and other fields. Based on their function, additives can be classified into plasticizers, stabilizers, flame retardants, catalysts, dispersants, defoamers, etc. Their production process typically involves the physical mixing or chemical reaction of multiple raw materials.

[0003] During production, the weighed raw materials need to be poured into the mixing device, and then the mixing components will disperse and mix them evenly. In the production of some additives, in order to prevent the raw materials from coming into contact too early and causing side reactions, it is also necessary to add different raw materials in stages. The existing technology usually adopts the method of pouring in all at once. This method will cause a large amount of liquid raw materials and solid raw materials to come into contact instantly, which is prone to forming lumps and agglomeration. The occurrence of this phenomenon will significantly increase the difficulty of mixing raw materials and affect the mixing effect. Utility Model Content

[0020] Reference Figures 1-2 A raw material feeding device for the production of additives includes a support 1, on which a plurality of storage tanks 2 are fixed for holding liquid raw materials and solid raw materials;

[0021] A sleeve 3 is vertically fixed at the bottom center of the storage bin 2. A rotating shaft 4 passes through the sleeve 3. The upper end of the rotating shaft 4 is rotatably engaged with the top of the storage bin 2 through a bearing. A motor is fixedly installed on the top of the storage bin 2. The output shaft of the motor is connected to the upper end of the rotating shaft 4. The motor is a stepper motor, which intermittently drives the rotating shaft 4 to rotate.

[0022] The lower end of the rotating shaft 4 also passes through the storage tank 2 through the bearing and is fixedly provided with the control plate 5. The surface of the control plate 5 is in contact with the bottom of the storage tank 2. Several first feeding holes 6 are evenly opened at the bottom of the storage tank 2. Several second feeding holes 7 are correspondingly opened on the control plate 5. The second feeding holes 7 are intermittently aligned with the first feeding holes 6. The upper end of the storage tank 2 is provided with a feed inlet. The bottom of the storage tank 2 is fixedly fitted with a guide hopper 8. The bottom of the guide hopper 8 is connected to the stirring device used for the production of auxiliary agents.

[0023] Additionally, an installation ring 9 is fixedly sleeved on the upper end of the rotating shaft 4, and a connecting rod 10 is horizontally fixed on the installation ring 9. A scraper 11 is fixedly installed on the end of the connecting rod 10 away from the installation ring 9. The scraper 11 has an overall L-shaped structure, and the surface of the scraper 11 is in contact with the inner wall of the storage tank 2. When the motor drives the rotating shaft 4 to rotate, the rotating shaft 4 will synchronously drive the scraper 11 to move around the inner wall of the storage tank 2 through the connecting rod 10, scraping off the raw materials attached to the inner wall and reducing the waste of raw materials.

[0024] Several dispersing blades 12 are fixedly provided on the side of the scraper 11 near the sleeve 3. For some powdery raw materials, dispersing blades 12 can be added in the storage tank 2. This is because powdery raw materials are prone to clumping. Therefore, when the rotating shaft 4 drives the scraper 11 to rotate, the dispersing blades 12 on the scraper 11 will rotate accordingly, so that the raw materials can pass smoothly through the first feeding hole 6 and the second feeding hole 7.

[0025] Several first feeding holes 6 are evenly distributed in multiple groups around the circumference, and the first feeding holes 6 in each group extend evenly in the radial direction. The structure of several second feeding holes 7 is the same as that of several first feeding holes 6. During the rotation of the material control plate 5, the raw material can fall from the channel at different radial positions, so that the raw material has enough space to be fed.

[0026] The bottom cross-section of the storage bin 2 is set in an inverted trapezoidal structure. When the raw material is stored in the storage bin 2, the raw material will naturally converge towards the center of the bottom of the storage bin 2 under the action of gravity. When the channel formed by the second feeding hole 7 on the control plate 5 and the first feeding hole 6 on the storage bin 2 is opened, the raw material can fall through the channel more smoothly.

[0027] The control plate 5 includes an integrally formed plate body 51 and a sleeve 52. The sleeve 52 extends downward at the middle of the plate body 51. The inner diameter of the sleeve 52 is adapted to the outer diameter of the rotating shaft 4. The sleeve 52 is detachably connected to the rotating shaft 4 by screws. The operator only needs to use tools to tighten the screws to remove the control plate 5 from the rotating shaft 4 and fix the control plate 5 to the rotating shaft 4. By setting the control plate 5 to be detachably connected to the rotating shaft 4, the replacement and maintenance of the control plate 5 are facilitated.

[0028] Working principle: When using this device, the operator first adds the weighed raw materials for auxiliary production into each storage tank 2. The motor controls the rotating shaft 4 to rotate, and the rotating shaft 4 drives the control plate 5 to move synchronously. This causes the channel formed by the second feeding hole 7 on the control plate 5 and the first feeding hole 6 at the bottom of the storage tank 2 to open and close intermittently. When the channel is open, the raw materials in the storage tank 2 will fall from the channel under the action of gravity and enter the subsequent mixing device through the guide hopper 8 fitted at the bottom of the storage tank 2. By controlling the motor, the duration of the channel opening can be precisely controlled, thereby adjusting the feeding speed of the raw materials and realizing the batch feeding of the raw materials.

[0029] This solution uses an intermittent raw material addition structure to allow the raw materials to gradually enter the mixing stage, thereby effectively avoiding large-scale contact of raw materials at once. This allows the raw materials to be more thoroughly mixed during the mixing stage, thus improving the mixing effect and ensuring the quality of additive production.

[0030] The motor of this invention achieves coordinated operation through electrical connection with the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
